Introduction to LM358

Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to share my knowledge about Introduction to LM358. LM-358 consists of two independent high gain frequency compensated operational amplifier. They are specially designed to operate from a single supply or split supplies over a wide range of voltages. LM-358 have lot of amazing features associated with them. These features include wide supply ranges, low supply current drain, independent of supply voltage, wide unity gain bandwidth, ground includes I common mode input voltage range, low input bias, open loop differential voltage gain, internally frequency compensation etc. LM 358 has a lot real life applications e.g. Operational Amplifier (Op-amp) circuits, transducer amplifiers, DC gain blocks etc. LM-358 is available in as small size as chip. It is most commonly used device due to its cost efficiency. [otw_is sidebar=otw-sidebar-7]

Introduction to LM358

LM 358 consists of two independent high gain frequency compensated Operational Amplifier (Op-amp). These are designed for the operation of this device from single supply or split supplies for a wide range of voltages. LM-358 real life applications include DC gain blocks, active filters, transducer amplifier, Op-amp circuit design etc. Further detail about LM 358 will be given later in this tutorial.
1. LM358 Pinout
  • LM 358 has eight (8) pins in total having different individual functions associated with each of them.
  • All the pins along with their sequence number are given in the table shown below.
2. LM358 Pins Configuration
  • A properly labeled pin diagram of any device results in better standing of the user.
  • I have made a completely labeled diagram of LM-358 diode along with its animation.
  • The complete pinout diagram along with animation, symbolic representation and the real image of LM 358 is shown in the figure below.
3. LM358 Packages
  • LM 358 has four (4) different type of packages DSBGA, PDIP, TO-CAN and SOT-23(5).
  • All of theses packages along with their dimensions and part number are given in the table shown below.
4. LM358 Symbolic Representation
  • Symbolic for of a device shows its internal circuitry.
  • LM 358 symbolic representation is shown in the figure below.
   
5. LM358 Ratings
  • The voltage, current and power ratings of any device shows its power requirement i.e. how much amount of current and voltage is sufficient for its operation.
  • I have provided LM-358 current, power and voltage ratings in the table shown below.
6. LM358 Advantages
  • LM-358 has several different advantages, a few of which are given below.
  • There is no need of dual supply.
  • Compatibility with all forms of logic.
  • Two Op-amps, compensated internally.
  • Power drain suitable for battery operation.
  • Direct sensing near ground.
7. LM358 Applications
  • LM 358 has a wide range of real life applications, few of the major applications are given below.
  • DC gain blocks.
  • General signal conditioning.
  • Transducer amplifiers.
  • General signal amplification.
  • Active filters.
  • Operational amplifier circuits.
  • Current loop transmitters for 4 to 20mA.
7. LM358 Proteus Simulation
  • I have also designed a Proteus Simulation of LM358 which will give you better idea of its working.
  • In this simulation, I have designed a small automatic LED ON OFF circuit depending on LDR value.
  • The image is shown in below figure:
  • You can see in above figure that I have attached the LDR at input pins while the LED is attached at the output pin of LM358.
  • Now when LDR is dark, then LED will remain OFF but when LDR will come in Light then LED will also turn ON.
  • The variable resistor is used for sensitivity purposes.
  • In the below image I have shown its ON state:
  • You can see in above figure that now LED is ON because LDR is in LIGHT.

So, that is all from the tutorial Introduction to LM358. I hope you enjoyed this tutorial. If you have any kind of problem, you can ask me in comments, any time you want, without even feeling a bit of hesitation. I will try my level best to sort out your problems in a better way, if possible. Our team is also 24/7 here to help you out. I will explore further IC's and diodes in my upcoming tutorial and will surely share all of them with you as well. So, till then, Take Care :)
